One hypothesis is that Cloudera’s documentation does not reflect the latest developments in MariaDB. However, Cloudera explicitly states that the GTID replication mode is not supported in the case of Mysql: “Cloudera Manager installation fails if GTID-based replication is enabled in MySQL”. In return, the documentation of MariaDB specifies that their implementation of GTID is not identical to that of MySQL: “Note that MariaDB and MySQL have different GTID implementations, and that these are not compatible with each other”.

There remains a doubt as to the compatibility of the components deployed by Cloudera to MariaDB configured with GTID.
